“…However, some marine species could tolerate the higher ranges of toxic compounds without affecting their survival, such as the flathead gray mullet Mugil cephalus (Vagner, Lefrançois, Ferrari, Satta, & Domenici, 2008) and the European sea bass Dicentrarchus labrax (Montgomery, Simpson, Engelhard, Birchenough, & Wilson, 2019). Furthermore, tropical freshwater fish such as the tambacu Colossoma macropomum × Piaractus mesopotamicus also show a high range of tolerance to changes in water quality (Quaresma, Santos, Ribeiro, Leite, & Sampaio, 2020). Our results showed the first screening of biotic and abiotic parameters that affect the modification of seawater quality with different biomass loads.…”

The transport of live fish for aquaculture is a key issue in the domestication of new species. National level programs were developed in Peru for controlled repopulation of Peruvian grunt (Anisotremus scapularis), reared in extensive systems or ongrown in floating cages, but these were limited by inadequate knowledge of the best transport parameters to ensure survival. This study aims to identify the effect of low-density (21.18 ± 4.38) medium (31.77 ± 6.57) and high-density in (42.36 ± 8.76 kg m À3 ), corresponding to 6 (48), 9 (72), and 12 (96 indÁbag À1 ) indÁL À1 during the transport time (8, 10, and 12 hr), on survival. Also seawater temperature, dissolved oxygen, pH, ammoniacal nitrogen (NH 3 N), ammonia (NH 3 ), and ammonium (NH 4 ) were recorded at the end of transport. Survival at 8 and 10 hr at low-density was similar, but decreased at 12 hr. In contrast, all densities showed a greater effect after 12 hr of transport with 61.11 ± 17.35; 67.13 ± 7.13, and 70.49 ± 4.70% survival, respectively. Finally, the influence of the variables analyzed to contribute to survival and the sum of these, plus other parameters that were not measured, such as stress, leads to the conclusion of between 8 and 10 hr of transport time and not exceeding stocking density of 72 ind/bag (31.77 ± 6.57 kg m À3 ) should be used.

The production of high-quality seedlings is important to achieve better productivity in horticulture. Despite being well developed in conventional agriculture, there are few studies on aquaponic systems. The substrate choice in this integrated culture affects plant and economic feasibility. This study verified the effects of using Euterpe oleracea residue as a substrate for Coriandrum sativum seedling production in an aquaponic system with tambaqui, Colossoma macropomum. Five mixtures of Euterpe oleracea offal (0%, 25%, 50%, 75% and 100%) with coconut fiber, nourished by aquaponic wastewater, were evaluated. Water quality, fish and plant performance were analyzed during an 18-day experiment. Although total ammonia decreased from 5.17 mg L−1 to 0.64 mg L−1, nitrite and nitrate did not exceed 1 mg L−1 and 3 mg L−1, respectively. C. macropomum mean weight gain was 118.79 g and achieved high food assimilation, with a 0.86 feed conversion rate. Mean blood hematocrit (30.20 ± 5.99%) and glucose (59.5 ± 10.06 mg dL−1) indicates good physiological status of the C. macropomum. The use of the Euterpe oleracea offal mixture at 50% decreased by half the total fresh mass of Coriandrum sativum, down to 1.12 ± 0.30 g, but did not decrease dry mass (p > 0.05). When the mixture was above 25%, plant and leaf length were 8 cm and 3 cm smaller, respectively, and the number of leaves and stem base diameter were reduced by 34% and 40%, respectively. We do not recommend using more than 25% of Euterpe oleracea offal with coconut fiber for Coriandrum sativum seedling production in an aquaponic system.
